It delivers high levels of infrared heat with minimal visible light output, making it well suited as a primary heat source without interfering with your animal's natural day-night cycle. If you already run a Gold Infrared unit, this is the direct replacement lamp to keep it performing as intended.\u003c\/p\u003e\u003ch3\u003eWhat infrared means for your reptile\u003c\/h3\u003e\u003cp\u003eThe sun's energy reaches animals across three key spectrums: ultraviolet, visible light, and infrared. Infrared begins where the human eye stops — beyond 700nm — and is responsible for the warmth that drives thermoregulation in reptiles. Near infrared (IR-A, roughly 700–1400nm) and mid infrared (IR-B, roughly 1400–3000nm) penetrate the skin and surrounding surfaces, contributing directly to heat regulation within the animal. This supports digestion, promotes natural activity, and contributes to overall wellbeing in a way that broadly reflects how solar heat functions in the wild.\u003c\/p\u003e\u003ch3\u003eWhy gold infrared lamps work differently\u003c\/h3\u003e\u003cp\u003eThe gold lamp takes its name from the metallic sheen visible when the lamp is cold. In operation, it produces infrared that is effectively invisible to the human eye — the faint red glow at the lower end of the spectrum is the only visible output. Unlike a standard basking spot, infrared heat is projected across a wider area, allowing for a more natural basking gradient rather than a concentrated hotspot. Infrared is also unaffected by air movement, making it considerably more efficient at transferring heat than convection-dependent methods.\u003c\/p\u003e\u003ch3\u003eHow heat transfer works with this lamp\u003c\/h3\u003e\u003cp\u003eThis lamp works across all three mechanisms of heat transfer simultaneously. Radiation delivers direct infrared energy to your reptile and surrounding surfaces. Those surfaces then re-radiate stored heat through conduction. The surrounding air is also warmed via convection, much like a domestic radiator. This combination means the enclosure holds and distributes heat more evenly, reducing cold spots and supporting consistent thermoregulation.\u003c\/p\u003e\u003ch3\u003eUsing it correctly in your setup\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMust be used with a dimming thermostat — not a pulse or on\/off thermostat\u003c\/li\u003e\n\u003cli\u003eSuitable as the primary heat source within a terrarium or vivarium\u003c\/li\u003e\n\u003cli\u003eRich in both IR-A and IR-B wavelengths\u003c\/li\u003e\n\u003cli\u003e100w output — select wattage based on enclosure size and target temperature\u003c\/li\u003e\n\u003cli\u003eLow visible light emission means it will not disrupt your animal's photoperiod\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eUsed correctly with a dimming thermostat, the RS Gold Infrared Replacement Lamp 100w gives reptile keepers a reliable, biologically relevant heat source that works with the animal's natural physiology rather than against it.\u003c\/p\u003e","brand":"Peregrine","offers":[{"title":"100W","offer_id":54147679912273,"sku":"HRG101","price":27.32,"currency_code":"GBP","in_stock":true},{"title":"200W","offer_id":54147679945041,"sku":"HRG201","price":29.66,"currency_code":"GBP","in_stock":true},{"title":"400W","offer_id":54147679977809,"sku":"HRG401","price":33.74,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/0403\/8225\/files\/HRG101_1.jpg?v=1782596974","url":"https:\/\/viperia.co.uk\/products\/rs-gold-infrared-replacement-lamp-100w","provider":"Viperia UK","version":"1.0","type":"link"}
